岸壁效应对近岸航行船舶的安全性有重要影响,若操作不当常会造成船舶过度与岸壁接近而发生碰撞.文中以系列60(Cb=0.6)船型为例,采用一种一阶Rankine源面元法计算其在浅水域中以恒定速度沿3种不同岸壁航行时受到的横向力和首摇力矩,分析了水深、船到岸壁距离、岸壁倾斜角度以及下潜岸壁高度等对船舶受到的水动力的影响. 相似文献

A numerical study on bank effects in shallow channels is carried out by using a first-order Rankine source panel method. A
container ship sailing along a vertical bank and a sloping bank at different forward speeds, different water depths and different
distances between the bank and the ship hull is taken as example. The sway force and yaw moment acting on the hull are calculated
and the influences of the speed, water depth and distance between the bank and ship hull on the hydrodynamic force and moment
are analyzed. This study can provide insight into the bank effects, as well as to give guidance on ship manoeuvring and control
in restricted waterways, which is helpful to the navigation safety. 相似文献
